Urban revegetation and soil permeability solutions

Urban revegetation improves soil permeability, reduces flooding and supports biodiversity. Find out more about our solutions.

Risks of soil sealing

 - Icon

Increased flood risk

Rainwater no longer infiltrates, saturating drainage systems.

 - Icon

Groundwater pollution

Runoff carries pollutants to groundwater.

 - Icon

Degradation of neighboring soils

Waterproofing weakens neighboring soils, eroding them.

Increase in urban heat islands

The heat remains trapped, raising the temperature in the city.

Why rethink stormwater management?

As cities become more densely populated, soil sealing has multiplied the environmental risks to which our cities are exposed. Between recurrent flooding and urban heat islands, residents face increasingly difficult situations every year. Urban greening, coupled with better rainwater management, should make soil permeable again.

The challenges of urban revegetation for local authorities

Public authorities are playing an essential role in the ecological transition by implementing revegetation strategies. These initiatives, such as the National Urban Renewal Plan (PNRU), aim to improve urban comfort, make cities more adaptable to modern challenges and meet thermal standards. In this way, they support construction and energy renovation projects, while promoting a more sustainable environment.

Urban revegetation for a sustainable environment

Urban revegetation is essential to combat climate change, prevent flooding and reduce heat islands. Techniques such as landscaped valleys, green corridors and green roofs help improve soil permeability and rainwater management. These solutions help to protect biodiversity, refresh the environment and optimize the use of rainwater, while supporting sustainable development.

Regulations for urban green spaces

Regulations for urban revegetation are multiplying in France. For example, the 2021 Climate and Resilience Act mandates green roofs, and the Paris PLU includes requirements for green spaces. These actions aim to improve air quality, limit flooding and encourage biodiversity. Drainage solutions are essential to guarantee the effectiveness of green spaces.

Drainage solutions for soil permeability

Drainage panels like Drainbox are ideal for improving the permeability of urban soil. These solutions allow excess water to be collected and channeled into the urban drainage system, contributing to efficient stormwater management. Drainbox, made from expanded polystyrene, offers a durable, high-performance solution for all types of urban space, including green roofs and garden terraces.

Creating sustainable, attractive green spaces
